I l i No. 823,681.

To all whom. it may concern:

Be it known that I, CHARLES L. GULICK, a citizen of the United States, residing at Bridgeport, in the county ofFairield and State of Connecticut, have invented certain new and useful Improvements in Percussion- Fuses, of which the following is a specification.

This invention relates to improvements in percussion-fuses; and the object thereof is to provide a fuse ofthis typefof exceedingly 'l simple construction, employing but few and will not arm by accidental dro ping,l

parts, and which will be normally funarmed but which will be armed by the setack and will be reliable and effective in use. l

With the above objects in view my inven-v tion consists in the novel features of 4construction hereinafter fully described, particularly pointed out in the claims, and.

the parts; Fig. 4, a similar view o the basefuse; Fig. 5, a longitudinal sectional view of the nose-fuse, vshowing the position of the parts after the fuse has armed by the action of the set-back; Fig. 6, a similar view of the' base-fuse; Fig. 7, an enlarged view, in side elevation, of the lunger of the nose-fuse with the collapsible disks thereon; Fig. 8, a similar view showing a slightly different arran ement of the disks, and Fig. 9, a plan-view o one of thedisks. p A v Referring now more particularly to the base-fuse, 1 indicates the fuse-case, screw' threaded exteriorly', as-in the ordinary construction, for insertion in the base of the shell. rEhe inner end of the case is threaded inte-l riorly to receive the usual plug 2, carrying the primer 3. Arranged. .to move freely ongituinally in the fuse-case is a plunger 4, which ointed to eX lode the primer when broug t in contact t erewith upon 1mpactof the shell, while the 'opiplosite end there-A of is formed witha base 5, `W the case.

6 designates a `masking member having a 'ch centers it in slightlyta-pered bore to receive thelplunger y4'. This member is normally'held with its Specification of Lettersvatent.' Y

by two collapsible disks-7. These disks are of the plungen'and' thus `masking the sameformed substantially cup-shaped, with acentral perforation therein, whereby theymay be slipped upon the plunger with their larger ends in contact, as shown in Fig. 7, or with v v their smaller ends in contact, as illustrated base 5 of therpllunger an the inner end of the member 6. e disks, by reason of their ou shape,

v the set-back, which forces tlie masking member backward upon the plunger. By reason of the taper of the plunger andthe bore of the masking member u on set-back the lat- 'ter is wedged upon the ormer, with the point of said plunger projecting beyond the outer end of said member and the -by Fig.I 8, said disks bein -placed'between the l I are-very strong and cannot be `co llapsed or fiattened by the jar. orblow caused.

parts held to- I gether tomove as one upon impact ofthe shell. Upon impactof the shell the (plunger and masking member@ move forwar ly and the point lof the former comes 'into contact I with and explodes the primer.-

The disks are chea 1n construction, and by reason thereof an thequick and sim le manner in which the parts maybe' assemb ed the fuse can be constructed at a smaller cost than those in which a shear-pin is used and those of more complicated construction. v. The figures ofthe drawin illustrating the nose-fuse show a 'slightlyifl'erent arran egov .ment of the parte'l necessary in a fuse of t is In this form of fuse vthe plug 8' of V this) fusecase 1 carries thering-point or projection 9, while the plunger 10 is rovided with the primer 11. The mas ng member 6 and disks 7 are of the same construction as described, and the operation of the parts is the same as in the base-fuse. Said member instead of masking the firing-point covers the rimer until'rnoved backward by the set-baci;A when it moves a sufficient distance on the plunv er to permit the primer to contact with the v move forward on impact of the shell.

Havin thus fully describedmy invention,

what I c aim as new, and desire to securelby g-point when theparts- Letters Patent of the United States, is- 1. In a` ercussion-fus'e, a member adaptedto norma ly preventfcontact betweenfthe outer end projecting beyond the pointed 'end l primer andv firing-point, and -a substantially cup-shaped disk for holding said member in this position adapted to be collapsed or flattened by said member on setback.

2. In a ercussion-fuse', a member adapted to norma ly prevent contact between the primer and iring-point, and two substantially cup-shaped disks placed in contact for holding said member in this position adapted to be collapsed or flattened by said member on set-back caused by the iiring of the g 3. In a percussion-fuse, a fuse-case, a plunger movable longitudinally therein, a primer and a firing-point carried one by the plunger and the other by the fuse-case, a member movable on the plunger, anda substantially cup-sha ed diskA arranged on said plunger for holding said member in position preventin contact between the primer and firingpomt adapted to be collapsed or flattened by said member on set-back.

4. In a percussion-fuse, a fuse-case, a plunger movable longitudinally therein, a primer and a ring-point carried one by the plun er and the other by the fuse-case, a mem er movable on the plunger, and two substantially cup-sha ed disks 'arranged on said plunger for ho ding said member in position preventing contact between the primer and firing-point adapted to be collapsed or iattened by said member on set-back.

5. In a percussion-fuse, a fuse-case, a plunger movable therein tapered slightly, a

primer and a iring-point carried one by the plun er and the other by the fusecase, a mem er having a tapered opening to receive the plunger, and a collapsible disk on said and a iring-point, carried one by the plunv 'ger and the other by the fuse-case, a member movable on the plunger, and a bowed or arched member arranged on said plunger for holding said first-mentioned member in po.

sition preventing contact between the primer and the. ring-point, said bowed or arch-l shaped member adapted to be collapsed or Hattened 0n set-back.

In testimony whereof I aix my signature in presence of two witnesses.
